1. The problem statement, all variables and given/known data A shaft is turning at 73.8 rad/s at time zero. Thereafter, its angular acceleration is given by a = -10.1 rad/s2 - 4.44 t rad/s3. where t is the elapsed time. Calculate its angular speed at t = 2.58 s 2. Relevant equations 1/2(Angular accel formula)+ 73.8t+0= theta final 3. The attempt at a solution do i take the integral of the accel formula then the velocity the plug in 2.58?
